The present invention relates to the field of optical imaging, and, in particular, to a multi-aperture imaging system and application thereof.
Modern electronic products have been designed to be smaller and smaller due to the trend of pursuing compact technical products. The consumers also demand more and more on cameras that are integrated in electronic products like cell phones and music players. A mobile electronic product that provides similar photographing experience as a single lens reflex camera is an expectation to the consumers. Optical zooming is a critical performance and feature for a single lens reflex camera. Nevertheless, this feature may not be directly adopted by camera integrated on a mobile electronic product.
Specifically speaking, the mechanical zooming solution for single lens reflex camera is limited in compact mobile electronic products. If such solution is utilized, the height of the camera of the mobile electronic products will make the entire produce look very thick and heavy.
Another solution is to obtain desired zooming ratio by cropping and interpolating the image through software processing, which is the digital zooming solution. Unfortunately, images obtained in this means may end up having blurring imaging result during an enlarging process.
Another way to implement zooming is to utilize at least two apertures imaging processing system. A basic form of such imaging system can use at least two camera modules to capture the image of the target object collaboratively. Because the focal lengths of the camera modules are different, it can obtain images of different depths of field. Then, it can achieve the zooming of the entire imaging processing system through switching between different camera modules during the image capture and by the stored software algorithm, which does not require change of the focal lengths of the camera modules and therefore allows the entire imaging processing system having a smaller size.
In other words, each of the camera modules has a different field of view, such that it may utilize multiple camera modules and digital zooming to simulate optical zooming. It is understood that there are overlapped portions for the fields of view of different camera modules because image information of the target object captured through different camera modules may also have overlapping portions. Then, an image with diverse depths of field can be produced through software algorithm processing.
Along with the market demand for zooming ratio, the focal length of a long-focal length camera module of the imaging processing system with at least two apertures has become longer and longer. Nevertheless, it brings a challenge of arranging the positions of the camera modules of the entire imaging processing system while ensuring the high optical zooming performance at the same time, so as to collect enough information of the same target object and obtain an imaging processing system of higher definition and smoother switching between camera modules of various zooming ratios. This issue can be more complicated especially when there are multiple camera modules.

The electronic device 100 comprises an electronic device body 1000 and the multi-aperture imaging system 1, wherein the multi-aperture imaging system 1 is arranged and mounted on the electronic device body 1000 so as for capturing the image of the target object.
According to this preferred embodiment, the multi-aperture imaging system 1 comprises a wide-angle camera module 10, a mid-focal length camera module 20 and a long-focal length camera module 30, wherein the long-focal length camera module 30, the mid-focal length camera module 20 and the wide-angle camera module 10 can be operated coordinately, so as to achieve photographing performances of various depths of field through the focal lengths of the long-focal length camera module 30, the mid-focal length camera module 20 and the wide-angle camera module 10.
The electronic device body 1000 comprises a processing unit 2 and a display unit 3, wherein the processing unit 2 is communicationally connected with the display unit 3 and the multi-aperture imaging system 1 is operationally connected with the processing unit 2.
The processing unit 2 is electrically connected with the display unit 3 and operationally connected with the multi-aperture imaging system 1. The processing unit 2 is preloaded with software algorithm in order to control the switches among different focal lengths of the multi-aperture imaging system 1. Preferably, the display unit 3 is a touch screen that the user may directly communicate with the multi-aperture imaging system 1 or control the operation of the multi-aperture imaging system 1, by means of the display unit 3. The image information regarding the target object captured by multi-aperture imaging system 1 can be directly displayed on the display unit 3.
The electronic device body 1000 further comprises a front camera module 4, positioned on a front side of the electronic device body 1000 so as to face the user. The user may utilize the front camera module 4 for self-portrait and etc. . . .
It is worth noticing that the optical zooming of the multi-aperture imaging system 1 does not require any changes of the focal lengths of the wide-angle camera module 10, the mid-focal length camera module 20 and the long-focal length camera module 30. Rather, it coordinately utilizes the wide-angle camera module 10, the mid-focal length camera module 20 and the long-focal length camera module 30 to obtain different information of the target object. During the photographing process, it relies on switching among the wide-angle camera module 10, the mid-focal length camera module 20 and the long-focal length camera module 30 as well as the software algorithm loaded in the processing unit 2 so as to achieve the zooming of the multi-aperture imaging system 1 as a whole. This means that the multi-aperture imaging system 1 does not have to reserve internal space for zooming shifts, so that the multi-aperture imaging system 1 can be made further smaller in size.
It is worth mentioning that, for the multi-aperture imaging system 1, the wide-angle camera module 10 has a field of view: FOV1, the mid-focal length camera module 20 has a field of view: FOV2, and the long-focal length camera module 30 has a field of view: FOV3, wherein FOV1>FOV2>FOV3, wherein each of the fields of view, FOV1, FOV2 and FOV3 is angular field of view as shown in
According to the preferred embodiment, further referring to
For the multi-aperture imaging system 1, when the field of view FOV3 of the long-focal length camera module 30 is arranged adjacent to the field of view FOV2 of the mid-focal length camera module 20 and the field of view FOV2 of the mid-focal length camera module 20 is arranged adjacent to the field of view FOV1 of the wide-angle camera module 10, the focal length switching of the multi-aperture imaging system 1 can be smoother. For example, when it switches from a medium focal length to a relatively high focal length, because most of the conical shaped area of the field of view corresponding to the field of view FOV3 of the long-focal length camera module 30 is covered by the conical shaped area of the field of view corresponding to the field of view FOV2 of the mid-focal length camera module 20, the image information captured by the mid-focal length camera module 20 and the image information captured by the long-focal length camera module 30 have a larger overlapping information to help the switching between the two smoother. Similarly, when it switches from a lower focal length to a medium focal length, because most of the conical shaped area of the field of view corresponding to the field of view FOV2 of the mid-focal length camera module 20 is covered by the conical shaped area of the field of view corresponding to the field of view FOV1 of the wide-angle camera module 10, here for the same target object, the image captured by the mid-focal length camera module 20 and the image captured by the wide-angle camera module 10 have a large overlap area, so as to help the focal length switch and transient process from a focal length of the mid-focal length camera module 20 to a focal length of the wide-angle camera module 10 be more natural based on the support of more identical image information.
The mid-focal length camera module 20 is positioned adjacent to the long-focal length camera module 30 and the wide-angle camera module 10. Preferably, the mid-focal length camera module 20 is arranged closer to the long-focal length camera module 30 than the wide-angle camera module 10, that is helpful for the switching of high zooming ratio and the coordination of the mid-focal length camera module 20 and the long-focal length camera module 30 for photographing and producing a better photographing performance. Also, it facilitates a field of view area of the mid-focal length camera module 20 and the long-focal length camera module 30 which are arranged closer with each other to be covered and included by a field of view area provided by the wide-angle camera module.
According to some embodiments of the present invention, each of the FOV1, the FOV2, and the FOV3 satisfies the following conditions:
10°≤FOV3≤40°, 25°≤FOV2≤90°, and 50°≤FOV1≤180°.
Alternatively, according to some embodiments of the present invention, specific installation sites for two camera modules are designed based on the sizes of the field of view FOV3 of the long-focal length camera module 30 and the field of view FOV2 of the mid-focal length camera module 20 as well as the field of view FOV1 of the wide-angle camera module 10 and the field of view FOV2 of the mid-focal length camera module 20. The conical shaped area of the field of view corresponding to the field of view FOV3 of the long-focal length camera module 30 is mostly covered and included by the conical shaped area of the field of view corresponding to the field of view FOV2 of the mid-focal length camera module 20, and the conical shaped area of the field of view corresponding to the field of view FOV2 of the mid-focal length camera module 20 is covered and included by the conical shaped area of the field of view corresponding to the field of view FOV1 of the wide-angle camera module 10. Besides, the conical shaped areas of the field of view FOV3 and the field of view FOV2 are partially overlapped for the positions ≥5 cm from the end surface of the lens, and the conical shaped areas of the field of view of FOV2 and the field of view FOV1 are partially overlapped for the positions ≥3 cm from the end surface of the lens.
Specifically speaking, according to some embodiments of the present invention, at a position distanced from an end surface of a lens of the long-focal length camera module 30 is no less than (≥) 5 cm, a field of view area of the field of view FOV3 of the long-focal length camera module 30 is completely covered and included by a field of view area of the field of view FOV2 of the mid-focal length camera module 20. Further, at a position distanced from the end surface of the lens of the long-focal length camera module 30 no less than (≥) 20 cm, a distance I2 is defined between the long-focal length camera module 30 and the mid-focal length camera module 20. A radius R2 of the field of view area of the field of view FOV2 of the mid-focal length camera module 20 at that position satisfies the following condition: I2/R2≤0.125.
It is worth mentioning that with respect to a position distanced from the end surface of the lens of the long-focal length camera module 30 no less than (≥) 20 cm, a center of a section of the field of view corresponding to the field of view FOV3 of the long-focal length camera module 30 and a center of a section of the field of view corresponded to the field of view FOV2 of the mid-focal length camera module 20 are becoming closer, such that, as the shooting distance increases, the centers of the shot images of the long-focal length camera module 30 and the mid-focal length camera module 20 can be closer so as to produce a better photographing performance with respect to the area of the section of the field of view corresponding to the center.
More specifically, as the distance from the end surface of the lens of the long-focal length camera module 30 increases, the section area of the field of view area of the long-focal length camera module 30 will also increase accordingly because, with respect to the long-focal length camera module 30, the area of the field of view of the long-focal length camera module 30 is in conical shape, and that the farther from the tip of the conical area of the field of view of the long-focal length camera module 30, the larger the corresponding section area of the field of view of the long-focal length camera module 30.
Correspondingly, a section of the field of view area of the mid-focal length camera module 20 will also be larger and larger because, with respect to the mid-focal length camera module 20, the area of the field of view of the mid-focal length camera module 20 is in conical shape, and that the farther from the tip of the conical shaped area of the field of view of the mid-focal length camera module 20, the larger the corresponding section area of the field of view of the mid-focal length camera module 20. Besides, the overlapping portion of the field of view areas of the long-focal length camera module 30 and the mid-focal length camera module 20 will be increasing in this manner as well.
Nevertheless, with respect to the long-focal length camera module 30 and the mid-focal length camera module 20, the distance between the centers of the sections of the field of view of the long-focal length camera module 30 and the field of view of the mid-focal length camera module 20 on the same plane stays unchanged because these centers are positioned at the optical axes that are parallel to each other. However, the distance between these centers may be considered shortened with respect to the expanded sections of the fields of view.
For example, when the radius R2 of the section of the field of view of the mid-focal length camera module 20 is 10 cm, the section of the field of view of the long-focal length camera module 30 will be covered and included by the section of the field of view of the mid-focal length camera module 20. That is, the radius of the section of the field of view of the long-focal length camera module 30 is less than 10 cm. Then, when the distance I2 between the two centers is 1 cm, the ratio of the center distance I2 and the radius R2 of the mid-focal length camera module 20 is 0.1. When the distance from the end surface of the lens of the long-focal length camera module 30 has been increased and the radius R2 of the section of the field of view of the mid-focal length camera module 20 is 20 cm at some position, the section of the field of view of the long-focal length camera module 30 will be covered and included by the section of the field of view of the mid-focal length camera module 20 and has a radius less than 20 cm. When the distance between the two centers is still 1 cm, the ratio of the center distance I2 and the radius R2 of the mid-focal length camera module 20 is 0.05.
In other words, as the distance increases, with respect to the entire field of view area, the centers of the long-focal length camera module 30 and the mid-focal length camera module 20 are becoming closer, such that the pictures that the long-focal length camera module 30 and the mid-focal length camera module 20 shoot simultaneously will become more and more consistent, which facilitates the post compositing of the images captured through various camera modules.
Particularly, according to the preferred embodiment, the situation of I2/R2≤0.125 is defined as “coinciding”. Since the distance between the two centers with respect to the entire field of view area is equivalent to having a coinciding result, it is helpful for the post imaging process.
According to the preferred embodiment, at a positioned distanced from the end surface of the lens of the long-focal length camera module 30 no less than (≥) 20 cm, the center of the section of the field of view of the long-focal length camera module 30 and the center of the section of the field of view of the mid-focal length camera module 20 are coincided.
According to some embodiments of the present invention, I2 satisfies: 1 cm≤I2≤3 cm.
As for the mid-focal length camera module 20 and the wide-angle camera module 10, at the position distanced from an end surface of the lens of the mid-focal length camera module 20 for more than 3 cm, a field of view area of the field of view FOV2 of the mid-focal length camera module 20 is completely covered and included by a field of view area of the field of view FOV1 of the wide-angle camera module 10. Further, at position distanced from the end surface of the lens of the mid-focal length camera module 20 for no less than (≥) 10 cm, a distance between the mid-focal length camera module 20 and the wide-angle camera module 10 is I1, wherein a radius R1 of the field of view area of the field of view FOV1 of the wide-angle camera module 10 at that position satisfies the following condition: I1/R1≤0.125. It is worth mentioning that, for a position distanced from the end surface of the lens of the mid-focal length camera module 20 for no less than (≥) 10 cm, the center of the section of the field of view corresponding to the field of view FOV1 of the wide-angle camera module 10 and the center of the section of the field of view corresponding to the field of view FOV2 of the mid-focal length camera module 20 are becoming closer and closer, such that, as the shooting distance increases, the centers of the shot images of the mid-focal length camera module 20 and the wide-angle length camera module 10 can be more closer, so as to produce a better photographing performance with respect to the area of the section of the field of view corresponding to the center.
More specifically, as the distance from the end surface of the lens of the mid-focal length camera module 20 increases, the area of the section of the field of view area of the mid-focal length camera module 20 will also increase correspondingly because, with respect to the mid-focal length camera module 20, the field of view area of the mid-focal length camera module 20 is in conical shape, and that the farther from the tip of the conical shaped field of view area of the mid-focal length camera module 20, the section area of the conical shaped field of view area of the mid-focal length camera module 20 will be larger correspondingly. Correspondingly, the section of the field of view area of the wide-angle camera module 10 will also be larger and larger because, with respect to the wide-angle camera module 10, the area of the field of view of the wide-angle camera module 10 is also in conical shape, and that the farther from the tip of the conical shaped field of view area of the wide-angle camera module 10, the section area of the conical shaped field of view area of the wide-angle camera module 10 is larger correspondingly. Besides, the overlapping portion of the field of view areas of the mid-focal length camera module 20 and the wide-angle camera module 10 will be increasing in this manner as well. Nevertheless, with respect to the mid-focal length camera module 20 and the wide-angle camera module 10, the distance between the centers of the sections of the field of views of the mid-focal length camera module 20 and the wide-angle camera module 10 on the same plane stays unchanged because these centers are respectively positioned at the optical axes that are parallel to each other. However, in correspondence with the expanded sections of the field of views, the distance between their centers is being shortened. For example, when the radius R1 of the section of the field of view of the wide-angle camera module 10 is 10 cm, the section of the field of view of the mid-focal length camera module 20 will be covered and included by the section of the field of view of the wide-angle camera module 10. That is, the radius of the section of the field of view of the mid-focal length camera module 20 will be less than 10 cm. Then, when the distance I1 between the two centers is 1 cm, the ratio of the center distance I1 and the radius R1 of the wide-angle camera module 10 is 0.1. When the distance from the end surface of the lens of the mid-focal length camera module 20 has been increased and the radius R1 of the section of the field of view of the wide-angle camera module 10 is 20 cm at some position, the section of the field of view of the mid-focal length camera module 20 will be covered and included by the section of the field of view of the wide-angle camera module 10 and has a radius less than 20 cm. When the distance between the two centers is still 1 cm, the ratio of the center distance I1 and the radius R1 of the wide-angle camera module 10 is 0.05. In other words, as the distance increases, with respect to the entire field of view area, the centers of the mid-focal length camera module 20 and the wide-angle camera module 10 are becoming closer and closer, such that the pictures that the mid-focal length camera module 20 and the wide-angle camera module 10 shoot simultaneously will become more and more consistent, which facilitates the post compositing of the images captured through various camera modules.
Particularly, according to the preferred embodiment, the situation of I1/R1≤0.125 is defined as “coinciding”. Since the distance between the two centers with respect to the entire field of view area at this moment is equivalent to having a coinciding result, it is helpful for the post imaging process.
According to the preferred embodiment, at a position distanced from an end surface of a lens of the mid-focal length camera module 20 for no less than (≥) 10 cm, the center of the section of the field of view of the mid-focal length camera module 20 coincides with the center of the section of the field of view of the wide-angle camera module 10.
According to the preferred embodiment, the zooming ratio of the multi-aperture imaging system 1 is ≥4 (i.e. not less than 4). That is, the ratio of the equivalent focal lengths of the long-focal length camera module 30 and the wide-angle camera module 10 is no less than (≥) 4.
Preferably, according to one embodiment of the present invention, the ratio of the equivalent focal lengths of the mid-focal length camera module 20 and the wide-angle camera module 10 is 3, while the ratio of the equivalent focal lengths of the long-focal length camera module 30 and the wide-angle camera module 10 is 5. For the long-focal length camera module 30 as an example, the equivalent focal length is P1=F1*43.2/L, wherein F1 refers to the effective focal length of the long-focal length camera module 30, 43.27 mm refers to the length of the diagonal line of the 135 film, and L refers to the length of the diagonal line of the photosensitive area of the photosensitive element.
According to some embodiments, L refers to the length of the diagonal line of the photosensitive area of the CMOS photosensitive element. The effective focal length F1 refers to the focal length of a long-focal length lens of the long-focal length camera module 30, which is a fixed-parameter of the long-focal length lens. By the time the long-focal length lens has manufactured, the F1 is fixed. For a longer effective focal length F1 of the long-focal length lens, the length of the long-focal length lens has to be longer. The equivalent focal length P1 has to do with the overall focal length of the long-focal length lens and the photosensitive component, which is the focal length of the entire camera module.
When the photosensitive element of the long-focal length photosensitive component matching the same long-focal length lens is different, the equivalent focal length P1 will be different too. According to the present invention, a zooming ratio of the long-focal length camera module 30 and the wide-angle camera module 10, or the long-focal length camera module 30 and the mid-focal length camera module 20, or the mid-focal length camera module 20 and the wide-angle camera module 10 has to do with the contrast among the entire camera module, rather than the contrast of a lens of a camera module. In contrast to the effective focal length, the equivalent focal length has to consider the lens, the photosensitive component, and the factors regarding to the size of the photosensitive element. Hence, the ratio of the equivalent focal lengths is adopted here for representing the zooming ability of the multi-aperture imaging system 1.
Further, according to some embodiments of the present invention, the long-focal length camera module 30 is embodied as a periscope camera module, wherein the periscope camera module comprises a light turning unit adapted for turning light for 90 degrees for passing through an optical lens and being received by the photosensitive component for imaging. The photosensitive component, the optical lens, and the light turning unit are arranged along the width direction of the electronic device. The light reflected by the object and perpendicular to the width direction of the electronic device is turned by the light turning unit to pass through the optical lens along the width direction of the electronic device to be received by the photosensitive component for imaging. In this manner, it can effectively reduce the height of the long-focal length camera module 30, especially when the long-focal length camera module 30 has a larger focal length.
Further, the multi-aperture imaging system 1 comprises a flash 40. Preferably, the flash 40 is arranged at a center among the wide-angle camera module 10, the long-focal length camera module 30 and the mid-focal length camera module 20. The light emitted by the flash 40 is capable of satisfying the photographing needs of the wide-angle camera module 10, the long-focal length camera module 30 and the mid-focal length camera module 20, so as to assist the multi-aperture imaging system to achieve a better photographing performance.

According to the preferred embodiment, the third camera body 31, the third connection element 32 and the third connector 33 are arranged at the same axial line.
The third camera body 31 comprises a third lens unit 311 and a third photosensitive component 312, wherein the light passes through the third lens unit 311 to reach the third photosensitive component 312.
The long-focal length camera module 30 is embodied as a periscope camera module. The third lens unit 311 further comprises a light turning mechanism, a lens component and a processing element, wherein the light reached the light turning mechanism will be turned to enter a light path of the lens component to be received by the third photosensitive component 312 so as to allow the image information to be captured.
The processing element is capable of controlling not only the driving components, such as motor and etc., arranged in the third lens unit 311 so as to move the lens component for focusing, but also the motor movement of the light turning mechanism so as to adjust the position(s) and/or angle(s) of the reflector/lens/prism of the light turning mechanism. The third connection element 32 is electrically connected with the third lens unit 311 and the third photosensitive component 312, so as to transfer the information received by the third lens unit 311 and the third photosensitive component 312 to the third connector 33 through the third connection element 32 for output.

According to some embodiments of the present invention, the second connection element 22 can be a flexible circuit board. According to the preferred embodiment, the extending direction of the second connection element 22 to the second connector 23 of the mid-focal length camera module 20 is parallel with the extending direction of the third connection element 32 to the third connector 33 of the long-focal length camera module 30.
Further, the second camera body 21 is arranged adjacent to the third camera body 31, such that the field of view FOV3 of the third camera body 31 is mostly covered and included by the field of view FOV2 of the second camera body 21.
The wide-angle camera module 10 comprises a first camera body 11, a first connection element 12 and a first connector 13, wherein the first connector 13 and the first camera body 11 are connected and communicated through the first connection element 12. According to some embodiments of the present invention, the first connection element 12 can be a flexible circuit board.
According to the preferred embodiment, the extending direction of the first connection element 12 to the first connector 13 of the wide-angle camera module 10 is parallel to the extending direction of the third connection element 32 of the long-focal length camera module 30 to the periscope connector. The mid-focal length camera module 20 and the wide-angle camera module 10 are both arranged on the same side of the long-focal length camera module 30. Besides, the mid-focal length camera module 20 is arranged at the position closer to the light turning unit of the long-focal length camera module 30 than the wide-angle camera module 10, so as to allow most area of the field of view FOV3 of the third camera body 31 to be covered and included by the field of view FOV2 of the second camera body 21. Further, the field of view FOV2 of the second camera body 21 is mostly covered and included by the field of view FOV1 of the first camera body 11.
In other words, the length direction of the wide-angle camera module 10 is parallel to the length direction of the mid-focal length camera module 20 and the length direction of the wide-angle camera module 10 is also parallel to the length direction of the third camera body 31 of the long-focal length camera module 30. Alternatively, a light opening of the wide-angle camera module 10, a light opening of the mid-focal length camera module 20, and a light opening of the long-focal length camera module 30 are at the same axial line.
Specifically speaking, the multi-aperture imaging system 1 comprises the long-focal length camera module 30, the mid-focal length camera module 20 and the wide-angle camera module 10, wherein each of the long-focal length camera module 30, the mid-focal length camera module 20 and the wide-angle camera module 10 has a field of view, which are FOV3, FOV2, and FOV1 respectively, wherein FOV1>FOV2>FOV3. Besides, the field of view FOV3 of the long-focal length camera module 30 is arranged closer to the field of view FOV2 of the mid-focal length camera module 20 and the field of view FOV2 of the mid-focal length camera module 20 is arranged closer to the field of view FOV1 of the wide-angle camera module 10.

More specifically, as the distance from the end surface of the lens of the long-focal length camera module 30 increases, the area of the section of the field of view area of the long-focal length camera module 30 will also increase correspondingly because, with respect to the long-focal length camera module 30, the field of view area of the long-focal length camera module 30 is in conical shape, and that the farther from the tip of the conical shaped field of view area of the long-focal length camera module 30, the section area corresponding to the conical shaped field of view area of the long-focal length camera module 30 will be larger too. Correspondingly, the section of the field of view area of the wide-angle camera module 10 will also be larger and larger because, with respect to the wide-angle camera module 10, the field of view area of the wide-angle camera module 10 is also in conical shape, and that the farther from the tip of the conical shaped field of view area of the wide-angle camera module 10, the section area corresponding to the conical shaped field of view area of the wide-angle camera module 10 will be larger too. Besides, the overlap portion of the field of view areas of the long-focal length camera module 30 and the wide-angle camera module 10 will be increasing in this manner as well. Nevertheless, the distance between the centers of the sections of the field of views of the long-focal length camera module 30 and the wide-angle camera module 10 on the same plane stays unchanged because these centers are respectively positioned at the optical axes that are parallel to each other. However, the distance between these centers is shortened with respect to the expanded section of the field of view. For example, when the radius R3 of the section of the field of view of the long-focal length camera module 30 is 10 cm, the section of the field of view of the wide-angle camera module 10 will be covered and included by the section of the field of view of the long-focal length camera module 30. That is, the radius of the section of the field of view of the wide-angle camera module 10 will be less than 10 cm. Then, when the distance I3 between the two centers is 1 cm, the ratio of the center distance 13 and the radius R3 of the long-focal length camera module 30 is 0.1. When the distance from the end surface of the lens of the long-focal length camera module 30 has been increased and the radius R3 of the section of the field of view of the long-focal length camera module 30 is 20 cm at some position, the section of the field of view of the wide-angle camera module 10 will be covered and included by the section of the field of view of the long-focal length camera module 30 and has a radius less than 20 cm. When the distance between the two centers is still 1 cm, the ratio of the center distance 13 and the radius R3 of the long-focal length camera module 30 is 0.05. In other words, as the distance increases, with respect to the entire field of view area, the centers of the long-focal length camera module 30 and the wide-angle camera module 10 are becoming closer and closer, such that the pictures that the long-focal length camera module 30 and the wide-angle camera module 10 shoot simultaneously will become more and more consistent, which facilitates the post compositing of the images captured through various camera modules.
